WebMay 15, 2024 · 1 Answer. The batch size defines the number of video samples that will be introduce in each iteration of your model. The difference between the different values of batch size are the model weight's optimization. If batch size is equal to 3, the model will input the 3 sample videos and only after that 3 inputs, it will update the weights. WebAssume you have a dataset with 8000 samples (rows of data) and you choose a batch_size = 32 and epochs = 25. This means that the dataset will be divided into (8000/32) = 250 batches, having 32 samples/rows in each batch. The model weights will be updated after each batch. one epoch will train 250 batches or 250 updations to the model.
